I don't believe abortion is morally justifiable in certain situations but I do feel that the choice should be up to the woman and no one else.
I personally don't understand people who say "Why can't the woman just have the baby and put it up for adoption?" as if it's that easy. Not only is pregnancy a long process that no one should be put through if they don't wish to be, but babies don't get adopted immediately and I don't think it's fair to but them through that.
You are correct, pregnancy is a big thing to go through. However, this is the babies life, life is so important. It is so huge and important, 9 months of pregnancy is dwarfed in comparison. And yes, especially if the person was forced to engage in conception unwillingly and did not have any want for a baby it is not fair fir them to go through that. But bearing through it is on of the many hard parts of life. Life is unfair, it's just the way it is. But who do you think is ripped of more. A woman losing 9 months of her normal lifestyle and enduring labor and other pains instead, or a baby who never got to experience life at all? I think it's pretty obvious the aborted baby's predicament is much worse than the woman who didn't have an abortion.
I have more empathy for the woman who's already been born than for the unborn baby, actually.
